Genes affected

PARP14 (HGNC:29232): (poly(ADP-ribose) polymerase family member 14) This gene encodes a member of the poly(ADP-ribose) polymerase (PARP) protein family. The encoded anti-apoptotic protein may regulate aerobic glycolysis and promote survival of cancer cells. Increased expression of this gene has been reported in a variety of tumor types.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.190C>T (p.R64W) alteration is located in exon 2 (coding exon 2) of the PARP14 gene. This alteration results from a C to T substitution at nucleotide position 190, causing the arginine (R) at amino acid position 64 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
